Car was fine, got home, put it in park, and then the car just died. Tried to restart but it doesn't start anymore. found a spark plug wire disconnected, plugged in back in, no dice. Changed all plugs and wires, still no dice.

I found a wiring harness above the front left tire that was hanging and not connected to anything when I was changing the plugs. I can't find where to reconnect it to, which might be the source of my non-starting problem. It leads to the right hand side of the fusebox. Someone help! Where do I connect this thing??
